棉花Phi类GSTs基因家族进化机制解析

Glutathione S-transferase is one kind of ancient and multifunctional gene family. In plants, the Phi class GSTs genes play an important role under biotic or abiotic stress. In order to insight into the involution of Phi class GSTs genes in cotton genomes, twenty four phi class geneswere identified in Gossypium arboreum, Gossypium raimondii and Gossypium hirsutum genomes by bioinformatics in this study, furthermore, the sequences were highly conserved in Gossypium genomes. Gene structure analysis showed that most of the Phi class genes had 2 introns in Gossypium. According to phylogenetic tree analysis, gene loss of Phi class genes might be happened in Gossypium. These results provide basic data for further identifing the functions of phi class GSTs gene family in Gossypium.
